ASTM Barrier Standards

Engineered Moisture Defense

Positive-side hydrostatic head pressure demands zero-defect monolithic membranes. We engineer subterranean chemical barriers and blindside assemblies specified to exceed ASTM elongation and tensile thresholds under severe soil conditions.

Membrane Specifications

Substrate Chemistries

ASTM D5385 / 100 PSI

Pre-Applied Bentonite Composites

Engineered for zero-lot-line retention walls before structural concrete pours. Mechanical bonding creates a permanent grip that prevents lateral water migration even under active hydrostatic head pressure.

60-Mil Monolithic Film

Elastomeric Polyurea Barriers

Self-terminating spray application bridges substrate hairline cracking up to one-eighth inch. Cold-applied elastomeric formulations eliminate hot-work permits while ensuring seamless coverage across complex foundation wall penetrations.

ASTM C836 Compliance

Reinforced SBS Bitumen

Hot rubberized asphalt layered with heavy polyester scrim armor beneath pedestrian pavers and vehicular wearing surfaces. Resists structural deflection and continuous ponding moisture over post-tensioned parking garage decks.

Armor and Drainage

Mechanical scarification and grit-blasting achieve an ICRI Concrete Surface Profile of three to four. Cold joints receive hydrophilic waterstops and carbon-fiber joint reinforcement prior to priming.

Substrate moisture vapor emission rates are verified via calcium chloride testing before primer placement. Formulations penetrate concrete capillaries to maximize chemical and mechanical peel adhesion values.

Continuous high-voltage spark testing detects microscopic pinholes across one hundred percent of the cured membrane surface. Non-destructive electronic leak detection confirms monolithic barrier integrity before backfill.

Heavyweight dimpled drainage composites and dimpled HDPE protection boards shield the membrane from aggregate puncture during mechanical backfill compaction and direct subterranean water toward perimeter civil footers.
